Polymer lithium battery charging method and maintenance guide

Source: 2020 - 03 - 25 thy hits: lithium polymer battery charging method? Maintenance guide? Polymer lithium battery charging method at present, lithium rechargeable mainly adopts pressure limiting current limit in two ways. In the constant current ( CC) The early stages of the charging, the battery can accept the strongest power. With the stop charging process, enhanced the polarization effect, temperature, voltage rise. In constant voltage phase, called a trickle charge. Charge 10% of the electricity needs to be about 30% of the time. The current strength is reduced, temperature no longer increases. This process considering the total voltage of the battery pack or uniform voltage control, in fact, there is always a higher voltage, relative to other batteries has entered the stage of charge in the before. Similarly, in the process of discharge, discharge existed in the group of battery, overcharge over discharge of battery is fatal injury. Difference of large amount of gas, easy spontaneous combustion and the blasting, there was a severe phenomenon overcharge. Release the appearance change, but the failure rate is very fast, in normal use should be strictly avoided. , there is a known as parallel control, balance management new lithium battery charging method, can stop charging and discharging separately for each core energy saving management, balance control, the discharge of charge balance and dynamic balance balance the advantages of the two kinds of balance, although the work between monomer battery is different initial capacity, voltage, resistance, etc. , in the work to ensure that the relative strength and depth charge and discharge, gradually reached the height of the finishing line together. This method is especially suitable for large electric drive. Lithium battery, therefore, must use dedicated li-ion battery charger, especially pay attention to and the parameters of the battery used by the project form a complete set, want to, when the lithium battery, PCB is bound to battery maintenance, concrete scheme to avoid battery, discharge, fire, explosion, and the use of as much as possible to extend the battery into the old, yes, but the charge discharge, increase cell cycle time. Lithium polymer battery maintenance as lithium ion battery after transforming the new battery products, lithium polymer battery has certain precautions in the application. The first is the nature of lithium polymer batteries. Compared with lithium ion batteries, lithium polymer battery while improve the battery leakage problem, but did not fully resolved. In addition, lithium polymer battery can be made into ultrathin battery, thickness of 0. 5 mm, volume 3. 6 v400 ma, 10% higher than traditional lithium-ion battery power. In everyday use, also as lithium ion batteries, lithium polymer batteries are often afraid of internal short circuit, short circuit and overcharge the battery. The reason is due to the chemical nature very lively, lithium charge when the battery discharge, the battery will be heated from time to time, when the temperature is too high, it may burst. Therefore, when using the battery, try to be careful not to overload, is also a smooth plans to use the battery, don't let the battery run out, don't leave it charging continuous charging time is too long, In general, eight hours is the most appropriate) 。
